Students and Students are a place for students' aspirations to express their creativity. OSIS is formed based on the decision of the principal of the school which has a management body. Students who are involved in the OSIS management body must pass several criteria and requirements, including having communication skills and having a leadership spirit. Communication has a strong influence in shaping a person's attitude and leadership style in an organization. Students must be given briefings on attitudes and leadership styles so that they can direct, control their members and be responsible so that all parts of the work are coordinated in order to achieve company or organizational goals. One of the requirements to become an OSIS administrator is sitting at Ananda High School in Batam City, where the psychological condition of students is still unstable to lead. So that there are some conflicts that arise such as misunderstanding between members, task structure factors and organizational structures, for example, the unequal desire between the treasurer and chairman, personal factors, namely individuals must make decisions concerning themselves and the organization, environmental factors such as the absence of support from the environment or certain parties, differences of opinion, incomplete gatherings, many administrators who leave, there is leisure between members, poor time management and declining performance.

Xtrapol8: automatic elucidation of low-occupancy intermediate-states in crystallographic studies

Unstable states studied in kinetic, time-resolved and ligand-based crystallography are often characterized by a low occupancy, hindering structure determination by conventional methods. To automatically extract such structures, we developed Xtrapol8, a program which (i) applies various flavors of Bayesian-statistics weighting to generate the most informative Fourier difference maps; (ii) determines the occupancy of the intermediate state; (iii) calculates various types of extrapolated structure factors, and (iv) refines the corresponding structures.

Method of calculating the coherent scattering power of crystals with unknown atomic arrangements and its application in the quantitative phase analysis

Quantitative phase analysis is one of the major applications of X-ray powder diffraction. The essential principle of quantitative phase analysis is that the diffraction intensity of a component phase in a mixture is proportional to its abundance. Nevertheless, the diffraction intensities of the component phases cannot be compared with each other directly since the coherent scattering power per unit cell (or chemical formula) of each component phase is usually different. The coherent scattering power per unit cell of a crystal is well represented by the sum of the squared structure factors, which cannot be calculated directly when the crystal structure data is unavailable. Presented here is a way to approximate the coherent scattering power per unit cell based solely on the unit cell parameters and the chemical contents. This approximation is useful when the atomic coordinates for one or more of the phases in a sample are unavailable. An assessment of the accuracy of the approximation is presented. This assessment indicates that the approximation will likely be within 10% when X-ray powder diffraction data is collected over a sufficient portion of the measurable pattern.

Supervised linear classification of Gaussian spatio-temporal data

In this article we focus on the problem of supervised classifying of the spatio-temporal Gaussian random field observation into one of two classes, specified by different mean parameters. The main distinctive feature of the proposed approach is allowing the class label to depend on spatial location as well as on time moment. It is assumed that the spatio-temporal covariance structure factors into a purely spatial component and a purely temporal component following AR(p) model. In numerical illustrations with simulated data, the influence of the values of spatial and temporal covariance parameters to the derived error rates for several prior probabilities models are studied.

The effect of network structure on the purchase of virtual goods on social networking services

PurposeThis paper aims to identify the effect of social structure variables on the purchase of virtual goods. Using field data, it also tests whether their effects on a social networking service are dynamic.Design/methodology/approachTo achieve the research objectives, the authors have applied the random effects panel Tobit model with actual time-series corporate data to explain a link between network structure factors and actual behavior on social networking services.FindingsThe authors have found that various network structure variables such as in-degree, in-closeness centrality, out-closeness centrality and clustering coefficients are significant predictors of virtual item sales; while the constraint is marginally significant, out-degree is not significant. Furthermore, these variables are time-varying, and the dynamic model performs better in a model fit than the static one.Practical implicationsThe findings will help social networking service (SNS) operators realize the importance of understanding network structure variables and personal motivations or the behavior of consumers.Originality/valueThis study provides implications in that it uses various and dynamic network structure variables with panel data.

Partial structure factors derived from coarse-grained phase-separation dynamics on a disordered lattice with density fluctuations

The simplest and most time-efficient phase-separation dynamics simulations are carried out on a disordered lattice to calculate the partial structure factors of coarse-grained A-B binary mixtures. The typical coarse-grained phase-separation models use regular lattices and can describe the local concentrations but cannot describe both local density and concentration fluctuations. To introduce fluctuation for local density in the model, the particle positions from a hard sphere fluid model are determined as disordered lattice points for the model. Then we place the local order parameter as the difference of the concentrations of A and B components on each lattice point. The concentration at each lattice point is time-evolved by discrete equations derived from the Cahn-Hilliard equation. From both fluctuations, Bhatia and Thornton’s structure factor can be accurately calculated. The structure factor for concentration fluctuations at the large wavenumber region gives us the correct mean concentrations of the components. Using the mean concentrations, partial structure factors can be converted from three of Bhatia and Thornton’s structure factors. The present model and procedures can provide a means of analysing the structural properties of many materials that exhibit complex morphological changes.

Encouragement and Contracting Factors for Implementation of Dynamic Village Institutional Program and Adaptive Culture in Minahasa Tenggara District

One of the programs of the Ministry of Villages, Development of Disadvantaged Regions and Transmigration of the Republic of Indonesia based on sustainable development (Sustainable Development Goals) globally which consists of 17 goals which are then added one point as a foothold for the community, namely a dynamic village institutional program and adaptive culture that involves the local government as a working partner. The program of dynamic village institutions and adaptive culture aims at village development that is based on the cultural roots of the local community with the intention that everything built on a cultural basis will have extraordinary resilience and have good deterrence. This study uses Edwards III theory by considering four indicators as a factor in implementing public policies consisting of: Communication, Resources, Implementing Disposition, and Bureaucratic Structure. Factors that are considered as supporting factors in the implementation of the dynamic village institutional program and adaptive culture in Southeast Minahasa Regency are communication and the disposition of the implementer. Factors that are considered as inhibiting factors in the implementation of dynamic village institutional programs and adaptive culture in Southeast Minahasa Regency are resources and bureaucratic structure. Human and financial resources need to be improved. It is necessary to make standard operating procedures specifically for dynamic village institutional programs and an adaptive culture that has a clear position base in carrying out the program.

Single-particle excitations and metal-insulator transition of ultracold Fermi atoms in one-dimensional optical lattice with spin-orbit coupling

The dynamic structure factors reflecting the excitation spectra were investigated in a one-dimensional (1D) optical lattice with a spin-orbit coupling (SOC) effect. The results reveal that the single-particle excitations of both the density and spin dynamical structure factors are strongly reconstructed and split owing to the SOC effect, and a hat-like excitation band appears in the high-binding-energy region. The hat-like excitation band of the density dynamical structure factor exhibits an arc form, and has a pocket in the spin dynamical structure factor. In particular, only a gapless single-particle excitation point is left for both the density dynamical structure factor and spin dynamical structure factor when the SOC strength reaches a critical point at half-filling. A stronger SOC strength causes the gapless excitation points to disappear, which indicates that metal-insulator transition occurs. The metal-insulator transition only appears in half-filling and lightly doped regimes.
